TRANSPORT, STORAGE
[!] On receipt verify that the relay has not been damaged during transport. If damaged, do not install and immediately advise the transport service.
INSTALLATION
[!] Installation must comply with the rules of the standard EN60079-14 or with the current national standards. Before the installation in an explosive atmosphere, the installer must ensure that the relay is suitable for the classified area in consideration of the different inflammable substances present in the installation area (please verify the marking on the relay cover before installation). The relay must be installed only by qualified people with knowledge of electrical apparatus for explosive gas atmospheres and electrical installations in hazardous areas and has to be done with the relay and equipment at standstill, electrically dead and locked against restart.
MARKING
